During the recent underwater photo workshop with Kurt Amsler in St. Cyr-sur-Mer, I had the opportunity to check out my 2 achromats stacked onto a 100mm macro lens on some precious corals (corallium rubrum).

For the first shot, I used just one achromat on a full-sensor DSLR with 100mm macro. For the second one, I added another acromat. Two flashes were used. One in slave mode slightly behind/above the coral, the other one in front of the coral, right above the lens. I set the slave to higher power and kept the main one pretty low.

I think it’s amazing what level of detail macro beyond a 1:1 magnification scale can reveal. Hence I am keen to get the acromats ‘wet’ soon again.
